[courier-users] Debugging SMTP timeout problems
Hi all, I have been running Courier 0.39.1 on Debian Linux as my mail server (SMTP(S), POP3(S), IMAP(S)) for about a year now without any noteworthy problems. Today, the SMTP server started to act up: it accepts TCP connections virtually immediately, but then reacts only very, very slowly. Thus, most of the time, the connection times out on the client/peer side. Other services (POP3, HTTP, ...) work as perfectly as ever. Since there are no error messages in the logs, and the server's load is negligible (below 0.5 at all times), I'm suspecting a hardware error (e.g. harddisk), even though there are no hardware error messages in the logs as well so far. Can anyone give me some hints on how to debug the SMTP server's miserable performance?

I just read that the SpamCop DNS blacklist, which I'm using, has very recently dropped out, so this is probably the cause. Please ignore my mail -- if the problem persists when the SpamCop blacklist starts working again, I'll continue debugging.

Incoming SMTP connections have the client's IP address resolved via DNS, followed by an ident query. A nonfunctioning DNS server somewhere, or a broken firewall that's dropping identd packets, would slow things down. --- This SF.net email is sponsored by: eBay Get office equipment for less on eBay! http://adfarm.mediaplex.com/ad/ck/711-11697-6916-5 ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
[courier-users] Virtual acounts (long)
Hi,
Thanks to all that replied om my Kmail question. I got the point; I used
IMAP, not Maildir and got all maildir like stores in my window. Kmail
supports maildir and IMAP.
This time I try to get virtual hosting to configured. I'm not sure if I
should use 'virtual' here. The name *is* very confusing as was mentioned
recently on the list here. Also confusing is the chapter 'How do I implement
virtual hosting' in the FAQ (which I took from the web site).
First what I want to achieve:
I hold two domains: vandenbussche.nl and scouthout.nl. Both have an MX
record in the outside world pointing to my hostname/IP address of the cable
modem (fixed but not guaranteed). Mail is handled by Postfix/vmpop3d on
Mandrake 9.0. All machines on my LAN are in 'vandenbussche.nl'. All
'vandenbussche.nl' accounts have a real userid on the box. The
'vandenbussche.nl' accounts are read using POP3.
All mail to accounts in 'scouthout.nl' are immediately forwarded out again
via the standard alias settings in Postfix. So [EMAIL PROTECTED] gets
forwarded to [EMAIL PROTECTED], [EMAIL PROTECTED] gets forwarded
(aliased) to [EMAIL PROTECTED] . Most other accounts in scouthout.nl go out
again to hotmail-like adresses. It is just to give the members of the local
boyscouts group a nice email address. Works fine for two years already. Also
simple mailing lists are done this way.
Now I want to change my mailserver to Courier. That will me give the
posibility to use POP3, IMAP and webmail but I do not want to loose the
'old' forwarding trick for the nice email addresses for users that have an
email address already somewhere else.
I thought the FAQ ('How do I implement virtual hosting') would answer my
question... however:
The first userdb example tells me to use 'filename/[EMAIL PROTECTED]' when
userdb is a directory (which is true in the 0.42 release). Shouldn't that
read 'directory/john...'? I understand that this will create a
/etc/passwd-like lookup table for example.com users. What would the home
dir. be? /home/virtual/example.com/john? And the next user?
/home/virtual/example.com/pete? Must I do a 'maildirmake' in both
directories?
The second userdb command example for an account *without* home directory
sets both a 'home' and a 'mail' location. What is then the default (for
'mail') in the first example? And what would be the home directory then if
there is no home directory? Why is the system mailbox in
/home/virtual/example.com/john? That sounds like a home directory to me.
I would be very grateful for a full text example for dummies like me.
Thanks again for reading up to here and any advise.
Best regards,
Egbert Jan van den Bussche

At 04:49 PM 6/1/2003, you wrote: The first userdb example tells me to use 'filename/[EMAIL PROTECTED]' when userdb is a directory (which is true in the 0.42 release). Shouldn't that read 'directory/john...'? I understand that this will create a /etc/passwd-like lookup table for example.com users. That's correct. Example: /usr/lib/courier/sbin/userdb domain.com/[EMAIL PROTECTED] set home=/home/vmail/domain.com/bob uid=502 gid=502 What would the home dir. be? /home/virtual/example.com/john? Can be whatever you want. But what you list is the easiest to figure out later :-) And the next user? /home/virtual/example.com/pete? yes. Must I do a 'maildirmake' in both directories? you have to do maildirmake (or make the directories manually) for each user. and allo of those folders have to be owned by the account you're using as the virtual user. The second userdb command example for an account *without* home directory sets both a 'home' and a 'mail' location. What is then the default (for 'mail') in the first example? And what would be the home directory then if there is no home directory? Why is the system mailbox in /home/virtual/example.com/john? That sounds like a home directory to me. The thing is you can put the home directories for the virtual users wherever you want. I would be very grateful for a full text example for dummies like me. see above. Generally it's something like this (keep in mind, I'm probably doing it the hard way, but it works) Starting as root: su courier cd /home/vmail/$DOMAIN /usr/lib/courier/sbin/userdb $DOMAIN/$ADDRESS set home=/home/vmail/$DOMAIN/$USER uid=502 gid=502 /usr/lib/courier/sbin/userdbpw | /usr/lib/courier/sbin/userdb $DOMAIN/$USER set systempw /usr/lib/courier/sbin/makeuserdb exit su vmail mkdir /home/vmail/$DOMAIN/$USER cd /home/vmail/$DOMAIN/$USER maildirmake Maildir exit Thanks again for reading up to here and any advise. You can then create aliases in the /etc/courier/aliases dir. [EMAIL PROTECTED]: [EMAIL PROTECTED] Keep in mind that if you want the aliases to run through maildroprc, you can't use aliases, you'll have to create accounts, and then forward them using a .mailfilter file Rick (still learning, but trying to help nonetheless) Rick Steeves [EMAIL PROTECTED] http://www.sinister.net --- This SF.net email is sponsored by: eBay Get office equipment for less on eBay! http://adfarm.mediaplex.com/ad/ck/711-11697-6916-5 ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

[courier-users] Couriermlm and digest summary?
I'm using couriermlm to do digests. However, it appears to simply concatenate all of the posts into one document. Is it possible to get it to list all of the subject lines at the top of the digest, and then the body of the posts after that? thanks.

Verify that you actually ran 'make'. Running 'make check' immediately after './configure', without running 'make', will result in this error. --- This SF.net email is sponsored by: eBay Get office equipment for less on eBay! http://adfarm.mediaplex.com/ad/ck/711-11697-6916-5 ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
